A launch arm is grabbed and pulled backward against a spring force, and then is released to pivot forward and strike the basketball from the ball ready holder.

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation of U.S. application Ser. No.14/643,889 filed Mar. 10, 2015 for “BASKETBALL TRAINING SYSTEM” by D.Campbell, J. Campbell and A. Pan.

BACKGROUND

The present invention relates to sports training, and in particular to abasketball training machine with a motorized ball delivery device.

Training in sports involves the development of skills as well asphysical conditioning. The game of basketball requires physical strengthand conditioning, and also requires special skills. Successfuldevelopment of those skills requires repetition during practice.

Although it is a team sport, basketball presents opportunities for anindividual player to practice and improve his or her game without theneed for other players to be present. A player can develop ball handlingskills and shooting skills through individual practice.

Basketball players develop their shooting skills by shooting thebasketball from various locations on the court. If a second player isnot present to rebound, the shooter must rebound his or her own shots.The rebounding process can waste time that could otherwise be used intaking more shots. Over the past several decades, a number of ballcollecting devices have been developed to collect basketball shot at thebasketball goal (i.e. the backboard and the attached hoop and net). Theball collecting devices generally include netting and a frame forsupporting the netting around the basketball goal. The ball collectingdevices are often used with a ball delivery device, which directs theball back to the player.

Motorized ball delivery devices can return basketballs to a shooter atvarious locations on a basketball court. The ball delivery device canhave programs that determine which direction to return balls to theplayer, how many times to return the ball, etc.

Some basketball training systems also calculate shooting percentage. Thesystem monitors how many balls are delivered to the player (whichrepresents a number of shots taken), and how many shots go through thebasketball hoop (i.e. shots made). The system calculates a shootingpercentage based on the number of shots taken and the number of shotsmade.

SUMMARY

A basketball training system includes a ball delivery system in which abasketball is delivered to a ball ready holder located in front of aball launch mechanism. A launch arm is grabbed and pulled backwardagainst a spring force, and then is released to pivot forward and strikethe ball from the ball ready holder.

DETAILED DESCRIPTION

FIG. 1 shows a side view of basketball training machine 10. Basketballtraining machine 10 includes two main systems, ball collection system 12and ball delivery system 14.

Ball collection system 12 includes net 16, net frame 18, base 20, shotsmade counter 22 (which includes made shots funnel 24, shots made sensor26, and counter support frame 28), and upper ball feeder 30. Whenmachine 10 is used for shooting practice, net 16 is positioned in frontof a basketball backboard (not shown) so that the basketball hoop andnet (not shown) are immediately above shots made counter 22. The size ofnet 16 is large enough so that missed shots (which do not go through thebasketball hoop and net and through shots made counter 22) will still becollected by net 16 and funneled down to upper ball feeder 30.

Ball delivery system 14 includes ball launching machine 32, main ballfeeder 34, and ball ready holder 36. Ball launching machine 32 ispivotally mounted on base 20. The inlet of main ball feeder 34 ispositioned immediately below the outlet of upper ball feeder 30. Balllaunching machine 32 is pivotable about an axis that is aligned with theinlet of main ball feeder 34 and the outlet of upper ball feeder 30.Balls drop out of upper ball feeder 30 into main ball feeder 34. Ballsare delivered one at a time from main ball feeder 34 into ball readyholder 36 at the front of ball launching machine 32. Launch arm 38(shown in FIG. 2) launches the basketball out of holder 36 to a locationon the floor where the player catches the ball and shoots. The locationon the floor where the ball is delivered can be changed by pivotingmachine 32 with respect to base 20.

FIG. 2 is a perspective view of ball delivery system 14 from the frontand left of ball launching machine 32. In this view, ball collectionsystem 12 is not shown. Ball delivery system 14 includes ball launchingmachine 32, to which main ball feeder 34 and ball ready holder 36 aremounted. Ball launching machine 32 includes launch arm 38, bottomplatform 40 (which is pivotably mounted to base 20 of ball collectionsystem 12), and outer shell 42 (which encloses the ball launchingmechanism and controls that operate machine 32. Front face 44 of outershell 42 includes electronic front display 46, pre-launch warning light48 and front opening 50. Also shown in FIG. 2 are ball ready lever 52and toggle arm 54.

Balls that are collected by ball collection system 12 enter the upperend of main ball feeder 34 and directed downward and forward to togglearm 54, which stops further ball movement. When toggle arm 54 isactuated, it pivots to release a single ball to travel further downwardand forward into ball ready holder 36. As shown in FIG. 2, ball readyholder 36 slopes downward and rearward through opening 50 into balllaunching machine 32. As the ball rolls down ball ready holder 36 towardlaunch arm 38, it contacts ball ready lever 52. When ball ready lever 52is depressed by a ball in ball ready holder 36, it provides a ball readyinput signal to the control system of machine 32. This causes a motordriven cycle to be initiated in which launch arm is engaged and pulledbackward while a tension spring is extended. As the cycle continues,launch arm 38 is released and the spring force drives launch arm 38forward to hit the ball and launch it forward out of machine 32 and ballready holder 36.

FIG. 3 is a perspective view of ball delivery system 14 from the rearand right of machine 32. At the top of shell 42 are USB port 56 andconsole 58, which allow a user to input information and select operatingmodes of machine 32, and to receive outputs including data collected bymachine as well as menus, instructions, and prompts.

At the rear of machine 32 are ball distance adjustment knob 60 and balldistance pre-select plate 62. Knob 60 and plate 62 are used to changethe spring tension or preload on the spring that drives launch arm 38.The greater the preload, the further the distance the ball will bedriven by launch arm 38 when it is released. In the embodiment shown inFIG. 3, plate 62 contains diagonal notched track 64, which includes fivenotches at which the tension rod connected to adjustment knob 60 can bepositioned. The lower the position of knob 60, the greater the preloadand the farther the ball will be launched.

FIG. 4 is a perspective view of ball launch mechanism 70 built on baseframe 40, which is rotatably mounted to base 20 of ball collectionsystem 12. Ball launch mechanism 70 launches balls using launch arm 38,which is pivotally mounted by pivot pin 72 to arm support uprights 74.At its upper end, launch arm 38 carries grab pin 76. At its lower end,launch arm 38 carries cross bar 78. Mounted to cross bar 78 are bumpersor cushions 80, which engage arm support uprights 74 to stop rearwardmovement of the lower end of launch arm 38 (and limit the forwardmovement of the upper end of strike are 38). Bracket 82 is mounted tothe lower end of launch arm 38 and connects the forward end of throwspring 84 to the lower end of launch arm 38. The rear end of throwspring 84 is connected to the upper end of throw spring tensioner 86. Asshown in FIG. 4, the lower end of throw spring tensioner 86 is pivotallyconnected to platform 40. The position of throw spring tensioner 86, andthus the tension or preload of throw spring 84 is controlled by alinkage between ball distance adjustment knob 60 and tensioner 86. Thiswill be shown in FIGS. 5A and 5B.

Ball ready lever 52 is positioned above the upper end of launch arm 38in FIG. 4. Ball ready lever 52 is mounted at the top of supportframework 88, which extends upward from platform 40 and includes anumber of vertical and horizontal tubular members. Ball ready sensor 90is mounted adjacent ball ready lever 52, so that when a ball rollsbackward and downward in ball ready holder 36 and presses lever 52, ballready sensor 90 changes state to indicate that a ball is in place and isready to be launched.

The retracting and then release of launch arm 38 is performed by amotorized drive system that includes drive motor 92, crank arm 94, grabarm 96 with hook 98, guide arm 100, movable guide wheel 102, stationaryguide wheel 104, guide arm spring 106, and drive motor sensor 108. Crankarm 94 is fixedly connected at its inner end to shaft 110 of motor 92,and is pivotally connected at its outer end to the lower end of grab arm96. As crank arm 94 is rotated through a 360 degree cycle by motor 92,grab arm 96 is guided between movable guide wheel 102 and stationaryguide wheel 104. Guide arm spring 106 applies a spring bias to movableguide when 102 to keep guide wheel 102 in engagement with grab arm 96 sothat grab arm 96 is contained between movable guide arm 102 andstationary guide wheel 104.

During a cycle, grab arm 96 will be moved so that hook 98 engages grabpin 76 and pulls the upper end of launch arm 38 rearward against thestring force of throw spring 84. As the cycle continues, grab pin 76will be pulled rearward to a maximum distance. Further rotation of crankarm 94 causes hook 98 to disengage from grab pin 76, which releaseslaunch arm 38 to move forward and launch the ball sitting on ball readyholder 36. The distance that the ball will travel depends on the amountof preload applied to throw spring 84 through throw spring tensioner 86.

The cycle is limited to one rotation of motor shaft 110. Drive motorsensor 108 is engaged by crank arm 94 as the cycle is being completed,and causes the cycle to be ended.

FIG. 4 also shows rotation calibration sensors 112 that are mounted onplatform 40. These sensors are used to determine the center position ofplatform 40, which allows machine 32 to calibrate the rotationpotentiometer that keeps track of the positon on the floor where theball is being delivered.

FIGS. 5A and 5B show ball launch mechanism 70 with the mechanism forpreloading throw spring 84 in place. Both FIGS. 5A and 5B show launchmechanism 70 after grab arm 96 has released grab pin 76 and launch arm38 has moved forward and launched the ball. Bumpers 80 are positionedagainst arm support uprights 74. As seen, grab arm 96 is orientedvertically and hook 98 is rearward of grab pin 76. Shown in FIGS. 5A and5B are ball distance adjustment knob 60, ball distance pre-select plate62, track 64, clamp 114, tension rod 116, and spring assist 118. Tensionrod 116 is connected at its outer end to knob 60 by clamp 114, and isconnected at its inner end to throw spring tensioner 86. Spring assist118 has its lower end connected to tension rod 116 near throw springtensioner 86, and is connected at its upper end to support framework 88.The angle of tensioner 86, and thus the amount of tension preload onthrow spring 84, depends on which notch of track 64 is holding tensionrod 116. FIGS. 5A and 5B illustrate two of the possible positions oftension rod 116.

FIGS. 6A-6F illustrate a cycle of the drive system that retracts andthen releases launch arm 38 to launch a ball. In FIGS. 6A-6F, throwspring 84 is not shown for simplicity and clarity. The starting andending point for each cycle is with grab arm 96 in a verticalorientation and hook 98 rearward of grab pin 76 and launch arm 38. Thatposition is shown as the start/end position in FIG. 6A.

FIG. 6A shows the outer end of crank arm 94 in contact with drive motorsensor 108. Motor 92 is stopped, grab arm 94 is nearly vertical and isheld between guide wheels 102 and 104. The upper end of launch arm 38and grab pin 76 are at their forward most position. In response to asignal from ball ready sensor 90 indicating a ball is in position onball ready holder 36 (not shown), drive motor 92 is activated and beginsto rotate motor shaft 110 and crank arm 94 in a clockwise direction.

FIG. 6B shows the cycle at the point where crank arm 94 has rotated to aposition where grab arm 96 is lifted away from stationary guide wheel104. The spring bias provided by guide arm spring 106 to movable guidewheel 102 has caused grab arm 96 to pivot so that hook 98 moves forwardover grab pin 76.

FIG. 6C shows grab arm 96 pulling grab pin 76 and launch arm 38 rearwardas crank arm continues its clockwise rotation. Movable guide wheel 102and guide arm spring 106 keep hook 98 in engagement with grab pin 76.

FIG. 6D show grab pin 76 at its furthest rearward and downward position.Further clockwise rotation of crank arm 94 will begin to cause hook 98to disengage for grab pin 76, as illustrated in FIG. 6E.

In FIG. 6F, hook 98 has released grab pin 76 and the upper end of launcharm 38 has moved forward rapidly to strike and launch the ball. At thepoint shown in FIG. 6F, the cycle is not yet complete. Crank arm willcontinue to rotate in the clockwise direction until the outer end ofcrank arm 94 engages drive motor sensor 108. At that point, drive motor92 stops with the mechanism in the position shown in FIG. 6A.

FIG. 7 shows toggle arm actuator mechanism 120, which operates togglearm 54. Mechanism 120 includes motor shaft 122, cam 124, cam followerguide wheel 126, guide blocks 128 and 130, spring 132, toggle rod 134,and sensor 136. When a ball has been launched, ball ready sensor 90indicates that there is no longer a ball waiting in ball ready holder 36to be launched. That initiates cam drive motor 150 (shown in FIG. 9) torotate motor shaft 122 in a counterclockwise direction. As motor shaft122 rotates, cam 124 rotates and guide wheel 126 follows the contour ofcam 124. Spring applies a downward spring bias to toggle rod 134 toensure the guide wheel 126 and toggle rod 134 will follow cam 124. Whenguide wheel 126 and toggle rod 134 move downward, the upper end oftoggle rod 134 pulls the forward end of toggle arm 54 downward torelease one ball downward and forward into ball ready holder 36. Asmotor shaft 122 and cam 124 continue to rotate in a counterclockwisedirection, guide wheel 126 and toggle rod 134 are driven upward to blockany further ball from moving past toggle arm 54. The rotation of motorshaft 122 continues until sensor 136 signals that one completerevolution has been completed.

The coordinated operation of ball launch mechanism 70 and toggle armactuator mechanism 120 causes balls collected by ball collection system12 and delivered to main ball feeder 34 to be supplied one at a timeonto ball ready holder 36. When a ball is in position on ball readyholder 36, launch mechanism 70 initiates a cycle in which grab arm 96retracts launch arm 38 and loads throw spring 84, and then releaseslaunch arm 38 so that the spring force causes launch arm 38 to strikethe ball and launch the ball off ball ready holder 36 to the player.

FIG. 8 shows a view of ball launch mechanism 70 of ball launchingmachine 32 in which the mechanism for rotating ball launch machine 32with respect to base 20 can be seen. In addition, many of the componentsof ball launch mechanism 70 that have previously discussed are alsolabeled and can be seen in FIG. 8. Among those components that havealready been discussed are launch arm 38, bottom platform 40 (which ispivotably mounted to base 20 of ball collection system 12), balldistance adjustment knob 60, ball distance pre-select plate 62, anddiagonal notched track 64, arm support uprights 74, cross bar 78,bumpers 80, bracket 82, throw spring 84, drive motor 92, grab arm 96,guide arm 100, movable guide wheel 102, stationary guide wheel 104,guide arm spring 106, and drive motor sensor 108. Components of togglearm actuator mechanism 120 seen in FIG. 8 include cam 124, cam followerguide wheel 126, guide blocks 128 and 130, spring 132, toggle rod 134,and ball feeder sensor 136.

The rotation drive mechanism shown in FIG. 8 includes rotation gearmotor 140, rotatable spur gear 142, stationary spur gear 144, rotationpotentiometer 146, and potentiometer bracket 148. Platform 40 is rotatedwith respect to base 20 by rotation of rotatable spur gear 142 withrespect to stationary spur gear 144. Spur gear 142 is driven by rotationgear motor 140. Stationary spur gear 144 is mounted on a shaft that isconnected to base 20 (shown in FIG. 1). As rotatable spur gear 142rotates, base 40 and all of the components mounted to base 40 rotateabout the axis of the shaft on which stationary spur gear 144 ismounted. Rotation gear motor 140 can drive rotatable spur gear 142 ineither a clockwise or a counterclockwise direction. Potentiometer 146 isconnected to the shaft on which stationary spur gear 144 is mounted, andproduces a variable resistance that is a function of the rotationalposition of platform 40.
